Abstract:Marine microalgae，as primary producers in marine ecosystems，play a crucial role in material cycling and environmental monitoring. To systematically evaluate the toxic effects of heavy metal pollution on microalgae, this paper reviews the relevant domestic research progress. The paper analyzes the physiological and biochemical responses of marine microalgae under heavy metal stressfrom aspects such as biomass， photosynthetic pigment content， photosynthetic rate，antioxidant system，and lipid content; explores the differential impacts of heavy metal concentrations，and summarizes the detoxification mechanisms of microalgae against heavy metals. Future research should be conducted by combining big data technology with bioinformatics，providing scientific basis for marine environmental governance and sustainable development.

Key words:heavy metal; marine microalgae; growth and reproduction； physiological and biochemical function; toxic effect

随着工业化、城市化进程加快，大量重金属污染物，如汞（ Hg ）、镉（Cd）、铜（ Cu 、铅（Pb）、锌1 Zn) 和铁(Fe)等，通过工业废水、农业废弃物等途径排入海洋。（剩余4724字）
